Emergency Treatment and Nursing Care of a Patient with Multiple Injuries and Right Main Bronchus Rupture

Objective: To investigate the rescue and nursing process of a trauma patient with multiple injuries and rupture of the right main bronchus. Methods: A patient with multiple injuries and rupture of the right main bronchus admitted to the emergency department of the Shenzhen Hospital of the University of Hong Kong was selected as the research object on December 11, 2019. Results: In this case, the medical team treated the patient under the guidance of ATLS (Advanced Traumatic Life Support), and for the first time in our department, we used bronchoscopy to replace the double-lumen endotracheal tube for left lung single-lung ventilation, finally the patient was successfully treated. Conclusion: Through a literature search, it is found that the main bronchus rupture is less common in clinical practice. In the trauma group, the use of fiberoptic bronchoscopy and the replacement of a double-lumen tracheal tube for left lung single-lung ventilation can improve the treatment rate of such patients and is worthy of clinical application.

The Future of Preoperative Assessments-Could Simple, Affordable Headphones Help Professionals Communicate with Children Preoperatively?

Children undergoing anaesthetics for medical or surgical procedures need to hear to communicate, assent, consent and understand what is happening on the day of surgery. Temporary hearing loss secondary to a condition called glue ear (also known as Otitis Media with Effusion, OME) is common in children, affecting 80% of children at least once before the age of 10years. Surgery (tympanostomy tubes, ventilation tubes or grommet insertion operations) to provide a resolution for glue ear is one of the most common operations in children. Studies show that simple, affordable headsets that work via bone-conduction (BC) technology help children with glue ear related hearing loss. In hospitals globally, health professionals have challenges with communication whilst wearing face masks, PPE and social distancing which impact most on patients with a hearing loss. Affordable BC headsets to assist listening could potentially be a preoperative solution to improve communication, assent and anxiety in children with evidence of glue ear.

Foudroyant middle-ear pneumococcal inflammation with meningoencephalitis in a six-year-old girl

Introduction. Intracranial complications of otitis media still occur, despite great progress in the treatment of all forms of inflammation. These are serious conditions which are still life-threatening and require a fast and accurate diagnosis and an adequate treatment. We present an illustrative case of an acute, foudroyant, pneumococcal, suppurative otitis media with infection spreading into endocranium and development of meningoencephalitis and otic hydrocephalus. Case report. A 6-year-old girl was admitted to the University Children's Clinic because of fever, headache, vomiting and disorder of consciousness. Computed tomography scan of the endocranium and temporal bone has revealed brain edema and hypodense content in the left mastoid and timpanic cavity. The diagnosis of acute otitis media with meningoencephalitis was made and we started with intensive antibiotic treatment. Lumbar puncture and haemoculture were confirmed a pneumococcal infection. Otosurgical treatment was conducted too due to an inadequate reaction to conservative treatment. Firstly, left mastoidectomy with the implantation of ventilation tube has been performed, followed by radical tympanomastoidectomy because there was no improvement. Three weeks after the second operation, a magnetic resonance imaging of the endocranium was performed and an otic hydrocephalus was diagnosed. A neurosurgical operation was performed on the same day with the setting of the ventriculo-peritoneal shunt. Conclusion. Intracranial complications of acute otitis media in children are extremely rare and they require multidisciplinary treatment. Surgical treatment of the ear shouldn't be postponed and the choice of the type of otosurgical intervention should be individually adapted. Audiological and neurological complications of the disease are frequent and they further prolong and impair the treatment.

The main steps in treatment of the children with otitis media with effusion

361 children at age from 11 months to 18 years with otitis media with effusion (OME) were inspected after tympanostomy during 2013-2018 years. Treatment was carried out in accordance with the stages of OME: secretory, mucous, fibrous. The main diagnostic methods were: otoscopy, tympanometry, endoscopy, computed tomography. Surgical treatment may be required already at the secretory stage of the disease, as well as in all cases with mucous and fibrous stages of OME. In children with recurrences of OME and in patients with congenital cleft lip and palate, it is preferable to use long-wearing ventilation tubes and balloning of the auditory tubes. The effectiveness of surgical treatment of OME was 97.6%. The authors recommend dispensary observation of patients with OME for 12-24 months.

Otorhinolaryngological Management in Taiwanese Patients with Mucopolysaccharidoses.

Background: Mucopolysaccharidoses (MPSs) are lysosomal storage disorders wherein glycosaminoglycans accumulate because the enzymes that degrade them are insufficient. The earliest symptoms, which are the main reasons for seeking consultation, are otorhinolaryngological and commonly occur in MPS I, II, IV, and VI. This retrospective study aimed to determine the occurrence of otorhinolaryngological manifestations in MPS patients in Taiwan and to analyze the prognosis of surgical intervention, including its effect on symptoms.Methods: We reviewed 42 patients (30 males and 12 females), with a median age of 20.5 years, who had MPS (16.7% type I, 35.7% type II, 19.0% type IIIB, 21.4% type IVA, and 7.2% type VI). The following otorhinolaryngological manifestations were collected: annual number of upper respiratory tract infections (URTIs) and otitis media with effusion (OME) episodes, adenoid size, tonsillar size, and apnea-hypopnea index (AHI).Results: Among 42 patients, we found recurrent otitis media in 42.9% of the patients, hearing loss in 83.3% (mixed: 52.4%, conductive: 21.4%, and sensorineural: 9.5%), frequent URTIs in 47.6%, and obstructive sleep apnea syndrome in 35.7%. Moreover, 76% of the patients underwent ear, nose, and throat (ENT) surgery, including adenoidectomy, tonsillectomy, tympanostomy with ventilation tube insertion, tracheotomy, and supraglottoplasty.Conclusions: MPS patients had a high incidence of ENT problems. ENT surgery reduced the severity of hearing loss, degree of symptoms related to upper airway obstruction, and severity of respiratory tract and otological infections of patients with MPS.

Predictors of postoperative complications in paediatric patients receiving grommets – A retrospective analysis

BackgroundInsertion of middle ear ventilation tubes (MEVT), tympanostomy tubes or grommets is one of the most common paediatric surgical procedures performed by ENT surgeons worldwide. Outcomes may be complicated by postoperative otorrhoea and ventilation tube blockage. ObjectiveTo identify risk factors associated with early postoperative complications of MEVT insertion. MethodIn a case-control study, set in a tertiary hospital in Melbourne, Australia, 590 paediatric patients undergoing grommet insertion between February 2017 and February 2018, 311 patients (205 males & 106 females; median age of 3.86 years) met the inclusion criteria and had identical middle ear status bilaterally. InterventionTympanostomy tube insertion and postoperative topical otic antibiotic drops. Main outcome and measuresPatient age, gender, weight/BMI percentile, intraoperative middle ear status, number of previous grommets, type of surgery, season of surgery, diagnosis and time to first medical review were examined. The duration of topical otic antibiotic drops used and tube patency and presence of otorrhoea at 6-week postoperative review were also recorded. ResultsAt the first medical review, 8.7% of patients (n = 27) developed otorrhoea from one or both ears, 6.4% of patients (n = 20) had an obstructed MEVT in one or both ears. Exposure to intraoperative [IO] and postoperative [PO] antibiotic drops were significantly less associated with developing postoperative otorrhoea compared to non-exposure (IO: Odds Ratio [OR] = 0.15, 95%CI 0.04 to 0.57, p = 0.005; PO: OR = 0.21, 95%CI 0.58 to 0.76, p = 0.017). There were no statistically significant associations between antibiotic drop exposure and grommet blockage (p > 0.05). There was a significant association between developing postoperative otorrhoea and patients receiving surgery during the colder months of Winter/Autumn (OR = 3.17, 95%CI 1.14 to 8.84, p = 0.028), as well as patients aged less than 3 years (OR = 2.66, 95%CI 1.01 to 7.03, p = 0.049). There was a statistically significant association between serous effusions and grommet blockage compared to no effusion (OR = 4.03, 95%CI 1.03 to 15.7, p = 0.045). There were no statistically significant associations identified between otorrhoea and gender, weight/BMI percentile, intraoperative middle ear status, number of previous grommets, type of surgery, diagnosis and time to first medical review. There were no statistically significant associations between grommet blockage and age, gender, indication for surgery, concurrent surgery, season or number of previous grommets. Conclusions8.7% of patients developed otorrhoea within 6 weeks post-operatively. Undergoing the procedure during winter/autumn, age <3 years were associated with developing otorrhoea. Topical antibiotic exposure was inversely associated with developing postoperative otorrhoea. 6.4% of patients had grommet blockage. Presence of serous middle ear effusion intraoperatively was a statistically significant indicator for developing grommet blockage.

Investigation of the Factors Associated with Mortality in Catheter-Related Bloodstream Infections: Five-Year Observation

Aim: Intravenous catheter use can cause various infections ranging from infection at the site of catheter entry to bacteremia and colonization. The purpose of this study was to identify the causative micro-organisms, and effects on morbidity-mortality of catheter-related bloodstream infections developing over the last five years.&#x0D; Material and Methods: Data for 194 patients who underwent central intravenous catheter insertion in our hospital’s intensive care unit and other departments between November 2014 and August 2019 were analyzed retrospectively. Blood samples taken from the catheter or the catheter tip, and blood samples collected simultaneously from the peripheral vein were included in the study, and culture results were recorded. Patients’ demographic data and the effects of the factors identified on morbidity and mortality were subjected to statistical analysis.&#x0D; Results: Ninety-two (47.4%) of the 194 patients included in the study were female and 102 (52.6%) were male, and mortality rate was 62.4% (n=121). The frequency of underlying medical conditions such as asthma, congestive heart failure, and cerebrovascular event, and receiving treatments such as immunosuppression, transfusion, tracheostomy, nasogastric tube, and mechanical ventilation were higher in mortal cases than non-mortal cases. A total of two hundred and forty microorganisms were detected in 194 patients, 121 (50.4%) of which were Gram negative bacteria, while 68 (28.3%) were Gram positive bacteria, and 51 (21.3%) were Candida species.&#x0D; Conclusion: As a result, it was observed that the advanced age, underlying diseases and presence of resistant microorganisms were higher in mortal cases.

Rapid formation of a shelter-in-place using a combination of vortex flow and chemical oxidation for indoor environments containing neurotoxic gases

Neurotoxic gases constitute a threat to the health of civilian population and military personnel, but the existing rescue methods are passive and inefficient. Therefore, a new method that combines vortex flow with chemical oxidation is proposed to remove neurotoxic gas and rapidly form a shelter-in-place for indoor environment. The concentration and velocity of the poisonous gas were calculated by Computational Fluid Dynamics (CFD) simulations and verified by Particle Image Velocimetry (PIV) experiments. The effects of mass ratio of gaseous oxide chemicals to poisonous gases, number of oxide inlets, velocity at inlet of the ventilation tube, and the influence of the pollution source position on the volume of shelter and amount of poisonous gases over time were also investigated in order to clear poisonous gas and construct shelter as quickly as possible. The results show that the optimal conditions were as follows: mass ratio 2:1, numbers of oxide inlet 4, and the velocity at the inlet of ventilation tube 4 m/s, respectively. Moreover, the amount of poisonous gases and shelter formation time decreased with increase in mass ratio of gaseous oxide chemicals and the number of oxide inlets. Furthermore, the methodology is shown to be robust, because the amount of toxic gas was always less than LCt50 when the mass ratio was greater than 1:1, regardless of the location of toxic gas source. This work provides a reference for rapid formation of shelters and quick rescue under neurotoxic gas attack in indoor environments.

Titration of Parameters in Shared Ventilation With a Portable Ventilator.

Dual-patient, single-ventilator protocols (ie, protocols to ventilate 2 patients with a single conventional ventilator) may be required in times of crisis. This study demonstrates a means to titrate peak inspiratory pressure (PIP), PEEP, and [Formula: see text] for test lungs ventilated via a dual-patient, single-ventilator circuit. This prospective observational study was conducted using a ventilator connected to 2 test lungs. Changes in PIP, PEEP, and [Formula: see text] were made to the experimental lung, while no changes were made to the control lung. Measurements were obtained simultaneously from each test lung. PIP was titrated using 3D-printed resistors added to the inspiratory circuit. PEEP was titrated using expiratory circuit tubing with an attached manual PEEP valve. [Formula: see text] was titrated by using a splitter added to the ventilator tubing. PIP, PEEP, and [Formula: see text] were reliably and incrementally titratable in the experimental lung, with some notable but manageable changes in pressure and [Formula: see text] documented in the control lung during these titrations. Similar results were measured in lungs with identical and different compliances. Pressures and [Formula: see text] can be reliably adjusted when utilizing a dual-patient, single-ventilator circuit with simple, low-cost modifications to the circuit. This innovation could potentially be lifesaving in a resource-limited or crisis setting. Understanding the interactions of these circuits is imperative for making their use safer.

Assessment of Pediatric Middle Ear Effusions With Wideband Tympanometry.

To determine if wideband tympanometry (WBT) can differentiate types of middle ear effusion (MEE): serous, mucoid, and purulent. Prospective cohort study. Tertiary care children's hospital. Children who met American Academy of Otolaryngology-Head and Neck Surgery's guidelines for ventilation tube insertion had WBT after anesthesia induction but before tympanotomy. MEE was categorized into 1 of 4 comparison groups: serous effusion, mucoid effusion, purulent effusion, or no effusion. WBT measurements were averaged to 16 one-third octave frequency bands, and comparison of the absorbance patterns for each MEE type was performed through a linear mixed effects model. A total of 118 children (211 ears) were included: 47 females (39.8%) and 71 males (60.2%). The mean age was 2.73 years (95% CI, 2.25-3.22); mean weight, 14.35 kg (95% CI, 12.85-15.85); and mean Z score, 1.13 (95% CI, -0.64 to 2.33). Effusions included 61 mucoid (28.9%), 30 purulent (14.2%), and 14 serous (6.6%), with 106 (50.2%) having no effusion. No significant differences were found for sex, race, age, weight, or Z score among the 4 types of effusion (P < .05). WBT showed a significant difference in median absorption among the effusion groups (P < .001), with a medium effect size of 0.35. WBT has potential use to differentiate types of MEE and should be studied further as a tool for investigating how the natural history and management of serous and mucoid effusions may differ.

Emergence of Prevocalic Stop Consonants in Children With Repaired Cleft Palate.

Purpose This study determined the time course of the emergence of prevocalic stop consonants in young children with cleft palate following surgical repair. Method A total of 120 children in four cohorts from three institutions were followed from 12 to 24 months of age: (a) 24 with repaired cleft lip and palate (CLP), (b) 36 with repaired cleft palate only (CP), (c) 33 without clefts but with histories of frequent otitis media and ventilation tubes (OM), and (d) 27 typically developing (TD) children without clefts or OM. Emergence of prevocalic stops and symbolic language skills were determined during administration of the Communication and Symbolic Behavioral Scales Developmental Profile. Parametric survival models were fitted with and without covariates-recruitment site, gender, maternal education level, middle ear status, language ability, and age at surgery for children with clefts-to describe the time course of the emergence of prevocalic stops. Results The estimated age at which 80% of children demonstrated prevocalic stop emergence was 15.0, 15.3, 18.9, and 21.8 months for TD, OM, CP, and CLP groups, respectively (p < .001, unadjusted model). Both CP and CLP cohorts had a significantly longer time to stop emergence than either the TD or OM cohorts, even after adjusting for covariates. Abnormal middle ear status, lower symbolic language ability, and older age at palatal surgery were significantly associated with delayed stop emergence. Conclusions Survival model estimates show that four out of five children with repaired cleft palate will achieve emergence of prevocalic stop consonants by 19-22 months of age, corresponding to 9-12 months following palate repair. Clinical implications are discussed.

Ventilation tube non-function due to blockage in children: the frequency, course and effect on hearing. A prospective cohort study.

To assess the effect on hearing of non-functioning ventilation tubes due to blockage during the first six months post-operatively, using UK national guidelines. A prospective, observational study was conducted on 37 children who underwent bilateral ventilation tube insertion. Air and bone conduction thresholds were measured before and following surgery, and at one, three and six months post-operatively. Tube non-function was assessed by tympanometry supported by otoscopy. Post-operatively, an average of 21 per cent of ventilation tubes were non-functioning. Ears with non-functioning tubes had significantly (p = 0.0001) poorer mean air conduction thresholds than functioning tubes, with a magnitude of 6 dB HL. Ears with otorrhoea were most affected (15 per cent). At any one visit, the air-bone gap was closed to 10 dB or less in 76 per cent of ears. Non-functioning tubes reduced this to 56 per cent. Compared with tympanometry, otoscopy underdiagnosed tube non-function due to blockage by 22 per cent. Non-functioning of ventilation tubes occurs frequently and can be missed on otoscopy. Although it is associated with poorer air conduction thresholds, the magnitude of this difference is unlikely to warrant further intervention unless there is otorrhoea or recurrence of bilateral hearing impairment.

Postoperative controls of ventilation tubes in children by general practitioner or otolaryngologist? Study protocol for a multicenter randomized non-inferiority study (The ConVenTu study)

BackgroundOtitis media with effusion is the major cause of acquired hearing problems in children. Some of the affected children need surgery with ventilation tubes in the tympanic membrane to reduce ear complaints and to improve hearing, middle ear function, and health-related quality of life. This is one of the most common ambulatory surgeries performed on children. Postoperative controls are needed to assess that the tubes are functional, to evaluate whether hearing loss has been improved, and to handle potential complications. The follow-up may continue for years and are usually done by otolaryngologists. Nevertheless, there exist no evidence-based guidelines concerning the level of expertise needed for postoperative controls of the ventilation tubes. The aim of this protocol is to describe the ConVenTu study that evaluates whether postoperative controls performed by general practitioners (GPs) represent a safe and sufficient alternative to controls performed by otolaryngologists.Methods/designMulticenter randomized non-inferiority study conducted in clinical settings in seven hospitals located in Norway. Discharged children with ventilation tubes, aged 3–10 years, are allocated randomly to receive postoperative controls by either an otolaryngologist at the hospital where they had ventilation tube surgery or their regular GP. Study participants are enrolled consecutively until 200 patients are included in each group. Two years after surgery, we will compare the pure tone average of hearing thresholds (primary endpoint) and middle ear function, complication rate, health-related quality of life and the parents’ evaluations of the postoperative care (secondary endpoints).DiscussionThis protocol describes the first randomized non-inferiority study of GPs performing postoperative controls after surgery with ventilation tubes. Results from this study may be utilized for deriving evidence-based clinical practice guidelines of the level of postoperative controls after ventilation tube surgery which is safe and sufficient.Trial registrationClinicalTrials.govNCT02831985.

Otoacoustic Emissions in Children with Long-Term Middle Ear Disease.

Introduction: Otoacoustic emissions (OAEs) evaluate the functional status of the cochlea. Repeated otitis media (OM) can cause changes in the peripheral structures of the auditory system, and, in this way, middle ear infection may irreversibly damage the middle ear, or even the cochlea. Objectives: To analyze the results of transiently evoked otoacoustic emissions (TEOAEs) and distortion product otoacoustic emissions (DPOAEs) in individuals with a history of OM. Method: Participants with 8 to 16 years of schooling were split into two groups: a control group (CG) of 50 subjects who had no history of otological disease and an experimental group (EG) of 50 subjects who had a history of recurrent otitis in childhood and had consequently undergone myringotomy to insert bilateral ventilation tubes. All children underwent basic audiological assessment (tonal audiometry, speech audiometry, and immittance testing) and otoacoustic emission testing (TEOAEs and DPOAEs). Results: There were no significant differences between the groups when audiometrically tested via air and bone conduction. OAEs were found in all CG subjects. For the EG, there were no TEOAE responses in 17 ears and no DPOAEs in nine ears; response amplitudes were lower at all frequencies. The emission level and the signal-to-noise ratio were statistically different between the two groups, and OAEs in the EG were statistically smaller compared to the GC. Conclusion: In the EG, responses were more likely to be absent and were of statistically smaller amplitude compared to the CG. A history of repeated OM apparently interferes with the generation and transmission of TEOAEs and DPOAEs.

Balloon eustachian tuboplasty for patients with chronic eustachian tube dysfunction: a novel method for Iranian samples

Background and Aim: Balloon eustachian tub­oplasty (BET) is a recently developed and app­roved method for management of chronic eus­tachian tube dysfunction (ETD). In the present study we aimed to evaluate the safety and effi­cacy of this method in Iranian samples. Methods: In this prospective case-series study, we included 15 adult patients with chronic ETD who were resistant to previous medical manage­ments and/or ventilation tube use. All patients underwent baseline audiometry (pure tone audio­metry and tympanometry), Valsalva maneuver, EDT questionnaire-7 (ETDQ-7), and physical examination. Three to six months after the BET procedure, all patients underwent four evaluation methods again. Results: We found a significant improvement in the mean ETDQ-7 scores comparing pre- and post-test scores (p &lt; 0.0001). There was also a statistically significant decrease in the average air-bone gap from 40.55 at baseline to 27.22 after treatment (p &lt; 0.001). In the Valsalva test, 17 out of 18 study ears (92.3%) had a positive result after the surgery. Under tympanographic evalu­ation, 9 ears (50%) reported a conversion from type B to type A after treatment, 2 ears (11%) had a conversion from type B to C, and 7 ears (39%) showed no any change and stayed in type B after BET. Conclusion: As a novel method in Iran, BET can be an alternative safe treatment option for chro­nic ETD. Keywords: Balloon eustachian tuboplasty; eustachian tube dysfunction; Iranian

A simple method to estimate flow restriction for dual ventilation of dissimilar patients: The BathRC model.

With large numbers of COVID-19 patients requiring mechanical ventilation and ventilators possibly being in short supply, in extremis two patients may have to share one ventilator. Careful matching of patient ventilation requirements is necessary. However, good matching is difficult to achieve as lung characteristics can have a wide range and may vary over time. Adding flow restriction to the flow path between ventilator and patient gives the opportunity to control the airway pressure and hence flow and volume individually for each patient. This study aimed to create and validate a simple model for calculating required flow restriction. We created a simple linear resistance-compliance model, termed the BathRC model, of the ventilator tubing system and lung allowing direct calculation of the relationships between pressures, volumes, and required flow restriction. Experimental measurements were made for parameter determination and validation using a clinical ventilator connected to two test lungs. For validation, differing amounts of restriction were introduced into the ventilator circuit. The BathRC model was able to predict tidal lung volumes with a mean error of 4% (min:1.2%, max:9.3%). We present a simple model validated model that can be used to estimate required flow restriction for dual patient ventilation. The BathRC model is freely available; this tool is provided to demonstrate that flow restriction can be readily estimated. Models and data are available at DOI 10.15125/BATH-00816.

Neutrophil-lymphocyte and platelet-lymphocyte ratios in otitis media with effusion in children: Diagnostic role and audiologic correlations.

To investigate the relationship between hearing loss and complete blood count parameters including neutrophil, lymphocyte, platelet (PLT), mean platelet volume (MPV), neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) in children with otitis media with effusion (OME). The study group was formed by 244 paediatric patients who underwent ventilation tube placement because of OME, and was split into two groups as serous and mucoid. The control group included 112 individuals who have no hearing problems. Hearing levels were determined with pure tone audiometry in the study group, preoperatively, and control group. The blood parameters were compared between the serous, mucoid and control groups. The correlation analysis was performed between the blood parameters and hearing levels in the study group. The blood parameters were compared between the groups identified by hearing loss classification. There were significant negative correlations between hearing levels and each of NLR, PLR and MPV. There were significant positive correlations between hearing levels and each of the lymphocyte and PLT. According to the receiver operating characteristic (ROC) curves, serous OME can be estimated with 68% sensitivity and 61% specificity by the NLR value more than 1.1, and 77% sensitivity and 77% specificity by the PLR value more than 102.4. The ROC curve revealed that slight hearing loss could be estimated with 70% sensitivity and 73% specificity by the NLR value more than 1.31, and 78% sensitivity and 77% specificity by the PLR value more than 102.4. The present study revealed that NLR and PLR values were valuable parameters in the diagnosis of serous OME and predicting a hearing loss. These parameters may provide additional information to the audiogram that could influence the therapeutic decision.
